Aurum

Free Crash Game: Crash on Aurum

A rocket takes off and the multiplier climbs with it. Cash out at any moment to win your stake times the multiplier, or set an automatic cash-out before the round. If the rocket blows up first, the stake is lost.

Every round is shared by everyone playing, and its crash point is fixed in advance by a public hash chain, so you can check after the round that nothing was changed.

Theoretical return: 97%. Played with Crowns, which have no real-world value.
